Ron, I haven't found any permanent damage to the keybed, but I have found that if the horse is in the center of the keybed, the regulating, tuning and action bedding will change once the piano is back on its legs. Ask me how I know. Happens with verticals also. Last tuning is done off the piano dollies and on its own casters.
